Abstract: A 3D elastoplastic finite element model is established for stability and stress analysis of the cellular steel sheet pile structure under wave load by employing ABAQUS finite element software. Shell element is used to simulate steel sheet piles and connector of hinge is set to imitate the influence of relative rotation of steel sheet piles next to each other; Mohr-Coulomb constitutive model is adopted for soil; and contact elements are set to simulate sliding, splitting and closing between sheet pile and soil outside and inside cellular. Based on a case engineering, mode of failure, stability failure property and stress distribution are studied, considering the influence of parameters variation on stability and hoop stress analysis of the structure; and anylisis of shear deformation in the sheet pile walls is carried out; suggestion is made for sheet pile interlock tension in some surface sections for examination. Results show that connector of hinge has little influence on stability but has a certain influence on hoop stress. Shear deformation surface mainly occurs in the medial axis of the cellular cell, which is consistent with the conclusion of Terzaghi.

Key words: cellular sheet pile structure, finite element model, shell element, connector of hinge, stability, hoop stress
